This might sound like a slightly wappy idea - but - does anyone know if it's possible to obtain a periscope about 1.5 m long to which a camera can be attached at the bottom?
This is to do with a sump we've been exploring. It's gone up from 10 m depth to about 1 m depth but there are some large and ugly boulders between the far point and the airspace. It'd be useful to get some idea of what happens in the airspace (as this may help fine tune the best route to take when excavating / making safe the choke).
Or would we be better off rigging up a video camera and a bright lamp on the end of a long stick?
I'm fishing for suggestions here . . . . (seriously!)
